Abscess of breast associated with pregnancy, unsp trimester

This code signifies a localized collection of pus within the breast tissue that develops during pregnancy. It indicates an infectious process requiring medical intervention, specifically an abscess, without specifying the trimester of gestation.

Apply this code when documentation clearly states a diagnosis of breast abscess in a pregnant patient, and the specific trimester is not recorded or is unknown. This code is appropriate for cases where the abscess is directly linked to the physiological changes or vulnerabilities of pregnancy.

• Ensure documentation explicitly links the breast abscess to the pregnancy.
• Avoid using this code if the abscess developed postpartum (use codes from O91.2-).
• If the trimester is known, use a more specific code from the O91.11- series (e.g., O91.111, O91.112, O91.113).
